-- This file tests base conversions from string to a decimal number
-- and back to a string (in Scientific form)

-- Note that unlike other operations the operand is subject to rounding
-- to conform to emax and precision settings (that is, numbers will
-- conform to rules and exponent will be in permitted range).  The
-- 'left hand side', therefore, may have numbers that cannot be
-- represented in a decDouble.  Some testcases go to the limit of the
-- next-wider format, and hence these testcases may also be used to
-- test narrowing and widening operations.
